Description: Implements a suite of shrinkage estimators for multivariate linear 
    regression to improve estimation stability and predictive accuracy. 
    Provides methods including the Stein estimator, Diagonal Shrinkage,
    the general Shrinkage estimator, and Slab Regression (Simple and
    Generalized). These methods address Stein's
    paradox by introducing structured bias to reduce variance without requiring 
    cross-validation, except for 'ShrinkageRR' where the intensity 
    is chosen by minimizing an explicit Mean Squared Error (MSE) criterion. 
    Methods are based on Asimit, V., Cidota, M. A., Chen, Z., and Asimit, J. (2025)
